Subject: [PATCH RFC 2/9] sparse-vmemmap: Consolidate arguments in vmemmap section populate
Date: Tue,  8 Dec 2020 17:28:53 +0000	[thread overview]
Message-ID: <20201208172901.17384-3-joao.m.martins@oracle.com> (raw)
In-Reply-To: <20201208172901.17384-1-joao.m.martins@oracle.com>

Replace vmem_altmap with an vmem_context argument. That let us
express how the vmemmap is gonna be initialized e.g. passing
flags and a page size for reusing pages upon initializing the
vmemmap.
